Overview

PC Game Booster is a Windows utility that brings game-library management together with system tuning and hardware temperature monitoring. It suits players who want automatic launch-time optimization across games from several storefronts, rather than a standalone launcher. Its strongest case is the combination of reversible tuning and monitoring; the main caveat is that some performance-focused tools are reserved for Pro.

Key features

The manager imports games from Microsoft Store, Battle.net, Steam, Epic Games, Ubisoft Connect, and other platforms, and lets you add titles manually when they are missed. Automatic boosting on launch and one-click controls make it a practical option for players who want optimizations applied without setting up each game individually.

While games and applications are active, the utility allocates CPU, memory, and disk resources and restricts unnecessary background processes. Its System Optimizer adjusts system, internet, application, and visual-effect settings to help reduce lag and interruptions. That broad scope is useful when background activity or Windows settings are part of the problem, but it also means the changes affect more than a game library.

The hardware monitor tracks CPU, GPU, motherboard, and other component temperatures and alerts when they exceed optimal levels. PC Game Booster does not overclock hardware, and its optimizations can be undone by switching off Game Mode or restarting Windows. That reversibility is a sensible safeguard for users who do not want lasting system changes; temperature alerts, however, are monitoring rather than a fix for overheating.

Pricing

The Free plan costs 0.00 USD per free and includes basic game optimizations, suspension of unnecessary system features, game management, automatic boosting on launch, hard-drive defragmentation, and system monitoring. It is a reasonable starting point for players who want library management and basic tuning without a subscription, but it does not include Pro's real-time FPS and other optimizations.

PC Game Booster Pro costs 18.95 USD per year for a 1-year license, with device count selectable on the store. The stated starting rate is 1.58 /mo on an annual basis. Each license code covers one PC; additional licenses are available at a reduced price. Pro is the better fit for players who want its extra optimization tools and 24/7 priority support, while the Free plan gives up those paid capabilities. A 30-day Pro trial lets users evaluate the paid edition before choosing a license.

Platforms

PC Game Booster supports Windows 8.1, 10, and 11, including 64-bit editions, and requires .NET Framework 4.8 or later. Its interface supports Simplified Chinese, English, French, German, Italian, Japanese, Portuguese, Russian, and Spanish.

Who it's for

Choose PC Game Booster if you play on Windows, keep games across multiple storefronts, and want launch-time resource management, system tuning, and temperature alerts in one utility. It is less compelling if you only need a free game manager or do not want to pay for the Pro-only performance tools.

Pros and cons

Pros: Imports games from several major storefronts and allows manual additions, so less common or unrecognized titles can still be managed.
Pros: Combines resource allocation, system-setting adjustments, and temperature alerts, covering several common gaming-PC concerns in one tool.
Pros: Optimizations are reversible through Game Mode or a Windows restart, and the software avoids overclocking.
Cons: The Free plan omits Pro's real-time FPS and other optimization tools, limiting its appeal to players seeking the full performance feature set at no cost.
Cons: Each Pro license code covers one PC, so users with multiple gaming computers need additional licenses.

Verdict

PC Game Booster is a good match for Windows players who want a single utility to organize games, apply reversible launch-time tuning, and watch component temperatures. Its breadth is the main reason to choose it; look elsewhere if you need a free alternative with the Pro performance tools, or if a one-PC Pro license does not suit your setup.
